RSI (Relative Strength Index) FAQs
Common questions about rsi (relative strength index)
The default 14-period RSI works well for most traders. Shorter periods (like 7) are more sensitive and suit day trading. Longer periods (like 21) are smoother and better for swing trading.
Not automatically. Oversold doesn't mean 'buy now' - it means the asset has declined rapidly. Wait for RSI to turn up from oversold levels, or combine with other confirmation signals.
RSI divergence occurs when price and RSI move in opposite directions. Bullish divergence (price lower, RSI higher) can signal a potential reversal up. Bearish divergence (price higher, RSI lower) can signal a potential reversal down.
